The Operational Benefits of Combi Rollers

Asphalt compaction practices vary from contractor-to-contractor and region-to-region — larger asphalt paving projects generally rely on some combination of double-drum vibratory and pneumatic tire rollers to complete the work. The double-drum vibratory compactor provides the brute force of compaction while the pneumatic tire roller provides varied weight through ballasting, and a kneading action that results in excellent density, fewer voids and a well-sealed finish.

The continued adoption of combi rollers — a vibratory steel drum on the front and a sequence of pneumatic tires on the back — has provided another option for paving contractors that ultimately delivers the best attributes of each standalone design.

CASE Launches New Small-Frame Combination Vibratory Rollers

CASE Construction Equipment introduces the new DV23CC and DV26CC combination vibratory rollers. The new vibratory rollers compact with the front drum and deliver a smooth finish with rear pneumatic tires. An inline drum with tapered edge and high curb clearance offers precision compaction capabilities in tight spaces, and adjustable scrapers, an automatic vibration control system and a pressurized water system ensure a smooth, clean finish in a variety of asphalt applications.

With operating weights of 4,740 pounds and 4,916 pounds, and drum width of 39.4 inches and 47.2 inches, the DV23CC and DV26CC are ideal for walkways, residential driveways, bike paths, tennis courts, small parking lots and other small- to mid-size applications.
